IMPROVEMENT IN ADVERTISING-LAMPS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Beit known that I, EMIL Bonscn, of the city and county of San Francisco, State of California, have invented an Improved Advertising-Lamp and I do hereby declare the following description and accompanying drawing are suflicient to enable any person skilled in the art or science to which it most nearly appertains to make and use. my said invention. or improvements without further invention or experiment.

My invention relates to improvements in lamps such as are employed for street advertising; and

It consists- First, in the peculiar form of the lamp, by which the full eliect of the inside light is obtained and a convenient advertising surface provided upon two of its sides; and

Secondly, in an'improved device for securing the panes of glass in the sides of the lamp.

In order to explain my invention so that others will .beable to understand itsconstrnction and operation, reference is bad to the accompanying drawing forming a, part of this specification, in which-- Figurcl represents a side view, and

Figure 2. shows a transverse vertical section My advertising-lamp I construct preferably .in an oval form, as shown; but angular corners may be employed and the general form he of an oblong or elongated figure.

A represents anarrow plate or strip of any suitable metal.

This strip of metal is curved so as to form the upper half of the lamp, and is provided with a covered chimney, M. 1

The opposite ends of the curved metal strip or roof A are connected with the lamp or light-stand B, at

the bottom, by corner-posts or standards 0, which are constructed by bending twostrips ofmet'al after the manner and form shown and described in my Letters Patent No. 106,990.

Just above the panes D I) is an apron, E, which is.

secured to the roof A so as to project downward at an angle to it.

Beneath this apron are several small l1oles, i, through which the inside of the lamp is ventilated by admitting fresh air upon both sides of the'flamc.

Reflectors F F are secured to the roof inside of the 1amp,-upon each side of the light.

Thesereflectors can be made of plain or corrugated sheet metal, and are formed by bending the sheet metal so that each side will describe a parabolic curve. The two sides or wings are then bent backward from a central line until they assume the proper angle for reflecting the light toward the desired point, which in this case is upon the sides and bottom of the lamp.

The two oval sides of the 'lamp are protected by panes, G G, of ground glass, upon which the number of the house and name of a firm or other advertisement can be painted or otherwise displayed, and thus,

when the interior is lighted up, give an illuminated sign of great attractiveness.

. The painted advertisement will be equally as useful during the day time.

The panes- G G are held in place in the following manner, viz: 'A metallic strip, I, isformed into a trough of sufficient capacity .to admit the edge of the pane of glass. This strip is then bent into a curve somewhat smaller thanthe curve of the edge of the pane, so that when it -is in place it will form a metallic binding.

A screw, J, which is provided with an intermediate flanged head, It, is then screwed into the rim of the frame, so that this head shall bear upon the binding and thus keep the-glass in place.

The strip'I being bent to a smaller curve than the curve of the edge of the glass, it requires to -be pressed down a little, atits center, which binds the end firmly down upon the glass, while a slight spring is left to prevent the glass from breaking when the lamp is jarred or otherwise disturbed.

This metallic binding also prevents the pieces of glass from falling out in case it should be cracked or broken.

The whole device forms a neat and attractive advertising-lamp, which can beiconstructed very cheaply.

Having thus described my invention,

\Vhat I claim, and desire to secure by Letters Patent, is-

1. The above-described.advertising-lamp, made in an oval or oblong form, and provided with the glass panes D D, parabolic reflectors F F, and side panes G, substantially as and for the purpose above specilied.

2. The metallic binding I, in combination with thescrew J provided with a flanged head, It, for securing tiltlli ttfiim
